I've already posted this, on the SubCommittee and Fine Scaler Model sites.
There are two new sources, for Gato/Balao details, available from Periscope Film. The "Electrical Installations" and "Trim and Drain System" manuals have just been released, and can be seen on their site.
PLUS, the "Air Systems" should be along in a couple of weeks. You want to do interior detail, or under-deck detailing? These books are for you. If you're impressed by AOTS, these'll blow you socks off.
They plan to reprint the entire series (12 books), if they can find copies of the books.
